CONSTRUCTION OF FLOORS OR CElLlNGS.

SPECIFICATION forming part of Letters Patent No. 515,434, dated February 27, 1894.

Application filed February 27, 1893. Serial No. 463,925- (No model.)

To all wk/0112, it may concern.-

Be it known that I, JOHANNES FRANZ KLEINE, a subject of the King of Prussia, residing. at Essen-ou-the-Ruhr, in the Kingdom of Prussia, German Empire, have invented new and useful Improvements in the Construction of Floors or Ceilings, of which the following is a specification.

Floors and ceilings as heretofore constructed with iron beams are in many cases too com plicated, and require to be of too great a weight on account of the greater height necessitated by the arched construction of floors, and consequently are too expensive. and drying of the concrete arches require a considerable length of time, and such concrete arches exert too great a lateral pressure, even greater than stone arches; and lastly the appearance of such arched floors and ceilings is such as to restrict their application to subordinate localities. Y

Other constructions of doors and ceilings are most unsuitable because the materials employed are in great part plaster of paris, the physical properties of which require such floors and ceilings to be preserved from all wet or damp.

My present invention has for its object to obviate the above named defects. I will describe the same with reference to the accom= panying drawings, in which- Figure 1 shows a section of the floor transversely to the iron beams and Fig. 2 shows, a section on line a: m Fig. 1. Figs. 1 and 2 show corresponding views to Figs. 1 and 2 in which suspension irons n are employed in addition.

In order to construct a floor with iron beams that shall be suitable for all dwelling and other rooms, and that shall present a plain ceiling, or one with paneled recesses, there are introduced between the iron beams slabs formed of natural or artificial stone blocks 8 secured together by cement, hydraulic mortar, or the like Z) and having iron bars, placed The hardening on edge (1 introduced between the joints; or the said slabs are formed in position between the iron girders, like flat arches. The very slight transverse strains to which the blocks and their cementing material are subject, can be entirely taken by suspension irons '12, or other suitable supporting devices, which are connected to the iron bars a in any suitable manner. I

By the employment of the above described mode of construction a very advantageous result in the construction of iron girder floors is obtained.

The method of construction is very simple and requires no expensive arrangements.

The strength of the combined materials is utilized in a very advantageous manner, and a considerable carrying power is obtainedwith a comparatively small height of construction and moderate weight. Every prejudical lateral pressure, such as occurs with arched floors, is obviated.

The iron girder floors thus constructed are very suitable for all dwelling and other rooms, and afford a cheap construction combined with economy of space.

W'hat I claim is- 1. In combination with the ordinary girders arranged parallel to each other, fiangeless cross bars supported thereby and stone slabs supported by said cross bars, substantially as described.

2. In combination with the parallel girders, the cross bars,'the stone slabs having recesses between them to receive the cross bars and cover the same, and irons n embedded in the stone bridging the break between adjacent stones, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
